Be it known that I, CARL ADAM OARLsoN, director of Works, 9. subject of the King of Swed en and Norway, and a. resident of Stockholm, in the Kingdom of Sweden, have invented certain new and useful Improvements in Registering Devices in Automatic Scales, of which the following is 'e. specification, reference being bad therein to the accompany ing drnwingsw V This invention reletes'to e registering device in eutorne "c scales in which the platform is loweredeccording es thelond increases; and it has for its object recording theresnlt I Besides l'dfQSZtVlllg-Of time thusobteined in the weigh ng operations every possibility of errors in recording is excluded.

in. the accompanying drawings the device is shown as applied to roller-scales, in Figure lviewed in a front elevation and in Fig. 2 in len view: Fiigfiis n. detail view; and Figs. are resp'entirely an elevation and a J 4 section, of a nioditledform. Orprevio J knownpnrts ofthescalesonly the, rollers l 1, end thestnnderd 2 are shown, along which letter the former roll. The rollers 1 comprise eecn am de portion to which the numeral l, is applied, and a narrow por-' tion, (indicated at 1*.) Friction -rol lers 1 may, if desired, be arranged to press against. The load acts, as usual, on the bends 3, depending from the wide portions oi the rollers, while other handset are wound around the narrower parts of the rollers and connect the rollers with the standard 2, to the upper end of which they are secured.

By means of a. link 28, suitable lever motion,

or the like the motion upward of the roller is transformed into a revolving one at the toothed sector 5, which sets on a pointer 31,

set by I indicating the results on a graduated dial, (indicated at 3V.) .The registering device consists of the two rollers l-S6, journa1ed verticztlly at somedistance epartin the framework v I7, secured to the scales in some suitable man- The comparatively wide paper strip 8' nor. is wound on the rollers 6.6.in suche. manner as to be transferred from one to the ethereal; therol-lens are rotated.

The lever 17 is then brought back to or indicator 10, which is able to return to the its initial position. By this operation the lezero-mark when the weighing mechanism is 95 ver 20 is brought back in its former position unloaded even if the lever 17 should be held 0 and the lever 10 resumes the position shown for some time in its inner position.
